Does anyone have a 2019 Jayflight SLX264 with the iRV-29 radio in it? I canít figure out how to use the hdmi cable thatís hanging out of it or the white and red audio cable either. How does the six setting work on it? I canít seem to find an owners manual. Any help would be great! Thanks!

The HDMI cable on the back is part of the 'hdmi pass through' capability. My understanding is that you install the stereo and run an HDMI cable from the back to your monitor (be it a tv, head rest screen, etc) and then you plug your video source (DVD player, game console, etc.) Into the front HDMI port. The HDMI port on the front and the HDMI cable on the back are essentially connected together inside the unit.

This model is also subwoofer capable. So the red and white audio outputs on the back are likely line level outputs for your subwoofer connection. The should be RCA type plugs as found on the back of most component TV's (yellow, red, white cable)

I'm trying to figure out how to get sound from the TV out to the stereo speakers. My TV has Input for RC Jack's, but no Output. Will USB to USB work? HDMI to HDMI? Those are my only choices available. May be wrong place to ask this, but you had better luck finding things than I.

I pulled mine the other day to look at it, I give up on trying to connect the TV to the speakers. If you have a TV that will output audio through Bluetooth, you could connect that way. I'm going to replace it and the crappy speakers that came inside the trailer as soon as I have time.
